Thunbergia mysorensis, the Mysore trumpetvine or lady's slipper vine,[1] is a species of flowering plant in the family Acanthaceae. A woody-stemmed evergreen, this vine is native to southern tropical India.[2] The specific epithet mysorensis is derived from the city of Mysore.[2]
Thunbergia mysorensis often reaches 6m (20feet) and has long narrow medium green leaves. The dramatic and very large pendent hanging blossoms have individual flowers in a bold curved shape. This is enhanced by their being a rich saturated yellow, with maroon to brownish red outer tip coloring.[2] The vine blooms from spring to autumn.[2]
Thunbergia mysorensis is cultivated as a popular ornamental plant in tropical and sub-tropical gardens, conservatories and greenhouses.[2] It grows quickly in frost-free temperate climates, such as coastal Southern California, with flowers draping down from pergolas and other garden structures.[3] Its sweet nectar is attractive to sunbirds, a very small passerine bird, and hummingbirds.[2] It has gained the Royal Horticultural Society's Award of Garden Merit.[4] [5]
